Android : How can one drag an ImageView in Android?

I've spent some time researching this and still haven't found a great answer.

What I would like is to drag an ImageView around the screen. Not a drag and drop, but just an actual drag.

This tutorial has been helpful:

It works perfect, but it's designed to drag a bitmap, not an ImageView. I've tried replacing the Bitmap with an ImageView, but I'm not sure how the Canvas and ImageView interact in the onDraw method. I've tried imageView.draw(canvas); and that doesn't seem to work - the ImageView doesn't show up at all.

Any suggestions?

Thanks in advance.
